摘要:

作者身份验证试图回答两个未知作者的文档是否由同一作者撰写的问题。已经提出了一系列成功的技术方法来完成这项任务,其中许多是基于传统的语言特征,如n-gram。这些算法对于某些类型的书面文档(如书籍和小说)取得了良好的效果。然而,社交媒体的作者身份验证是一项更具挑战性的任务,因为消息往往相对较短,具有各种不同的类型和主题。在这一点上,基于n-gram等特征的传统方法取得了有限的成功。在这项工作中,我们提出了一个新的神经网络拓扑结构的相似性学习,显着提高了性能的作者验证任务,这样具有挑战性的数据集。

英文摘要:

Authorship verification tries to answer the question if two documents with unknown authors were written by the same author or not. A range of successful technical approaches has been proposed for this task, many of which are based on traditional linguistic features such as n-grams. These algorithms achieve good results for certain types of written documents like books and novels. Forensic authorship verification for social media, however, is a much more challenging task since messages tend to be relatively short, with a large variety of different genres and topics. At this point, traditional methods based on features like n-grams have had limited success. In this work, we propose a new neural network topology for similarity learning that significantly improves the performance on the author verification task with such challenging data sets.
